OPA622 ® OPA622 OPA622 Wide-Bandwidth OPERATIONAL AMPLIFIER FEATURES q LARGE SIGNAL BANDWIDTH: 150MHz (AP), 200MHz (AU) (Voltage-Feedback) q HIGH OUTPUT CURRENT: ±70mA q SLEW RATE: 1500V/µs (AP), 1700V/µs (AU) q DIFFERENTIAL GAIN: 0.15% q DIFFERENTIAL PHASE: 0.08° q EXCELLENT BANDWIDTH/SUPPLY CURRENT RATIO: 200MHz/5mA q LOW INPUT BIAS CURRENT: –1.2µA DESCRIPTION The OPA622 is a monolithic amplifier component designed for precision wide-bandwidth systems including high-resolution video, RF and IF circuitry, and communications equipment. It includes a monolithic integrated current-feedback operational amplifier block and a voltage buffer block, which, when combined, form a voltage-feedback operational amplifier. When combined as a current-feedback amplifier, it provides a 280MHz large-signal bandwidth at ±2.5V output level and a 1700V/µs slew rate. The output buffer stage can deliver ±70mA output current. The high output current capability allows the OPA622 to drive two 50Ω or 75Ω lines with ±3V output swing, making it ideal along with the low differential gain/phase errors for RF, IF, and video applications.
